Yes alankina already pointed it out, and it is wrong. Refcounting simply does not work in C#. Because all the helper classes, collections e.t.c, do NOT implement IDispose. That's the point. You cannot implement refcounting when half the standard library is working against you.

Well, it's not all that bad. You can write an extension method for IEnumerable that will return an object whose Dispose method disposes of the objects contained within the collection. Then you can write something like

using (myCollection.Disposer()) {
    ...
}

Anyway, C++ still has the advantage that an object will implicitly call its member objects' destructors after running its destructor, and that it'll call the destructors of the already-constructed member objects when an exception is thrown within a constructor. So yeah, point taken, C++ probably does somewhat better in that regard.

Both would be really stupid things to do and any non-newbie programmer in C++ knows better.

I wish! People mess up simple things like that all the time.
